, DRINKING-FOUNTAIN.

Specification of Letters Patent.

Application filed iranuar 7, 1918. Serial No. 210,626.

To all whom it may concern:

Be it known that I, PETER 'W. BLAIR, a citizen of the United States,residin at Quincy, in the county of Norfolk and gtate of Massachusetts,have invented a new and useful Drinking-Fountain, of which the followingis a specification.

My invention relates to improvements in drinking fountains of the typeknown as sanitary, and more especially to nozzles for such fountains,and consists of a certain peculiar nozzle attachable within the bowl ofa fountain of the said type, together with such connections and otherparts and members as may be necessary or desirable in order to renderthe device complete, serviceable, and eflicient, all as hereinafter setforth. 7 v

The primary object of my invention s to provide, for a sanitary drinkingfountain, a nozzle which throws astream of water at an angle to theperpendicular, or projects such stream laterally away from the dischargeor'ifice, outlet, or mouth of said nozzle, instead of straight upward,to the end that the normal drinking point is remote from the verticalplane of said outlet, and no water that has touched the lips of a persondrinking can come into contact with said outlet.

A further object is to provide a nozzle, such as I have just outlined,-which can be readily attached to or connected with a drinking-fountainbowl that has the customary central supply opening. V

'Still'another object is to furnish simple and convenient means forconnecting such a nozzle with a bowl which. is provided with a nipple inthe center of'the bottom thereof.

This nozzle and the elements of the fountain with which it is mostintimately connected andv associated are designed to be connected withsuitable supply and waste pipes or equivalent members, with which pipesor members are employed the customary pressure regulating andvalve-controlling means. p ,7

The fountain equipped with this nozzle is highly efficient as weR asbeing entirely sanitary.

Other objects and advantages will appear in the course of the followingdescription.

I attain the objects and secure the advanol: n; mrention by the meansl-ll'llS- trated in the accompanying drawings, in which Figure 1 is atop plan of a sanitary drinking fountain which embodies a practical formof my invention; Fig. 2, a central, vertical section through saidfountain, taken 011 lines 22, looking in the direction of the associatedarrow, in Fig. 1, and, Fig. 3, a side elevationof the nozzle detachedfrom the other elements.

Similar numerals refer to similar parts throughout the several views.

In the drawings a drinking-fountain bowl is represented at 1, which bowlis equipped with a nozzle 3, said nozzle having one end located'in theaxial center of said bowl and the other end at one side of or beyondsaid center. The nozzle 3 has an outlet or mouth 4 in the outer end andopening through said end at .the top thereof, the axial center of whichmouth is oblique to the axial center of the bowl 1.

The nozzle 3 as shown is an approximately horizontal, hollow memberhaving the oblique mouth 4 at or in the outer terminal and an opening 5in the bottom at the other terminal. Said nozzle is provided with asleeve 6 which has an exteriorly screw-threaded part 7 tapped into theopening 5. The sleeve 6 is interiorly screwthreaded and adapted tofit'and engage a nipple 8 that rises from the center of :the bowl 1, andsaid sleeve has a dome 9 that i The bowl 1 is designed and adapted to bemounted on a supply and waste casing '(not shown), which casing or thesupply pipe or equivalent member is provided with the necessary ordesirable elements of regulation and control, of'usual and well-knownconstruction and operation. An annular flange 12, on the underside ofwhat maybe termed the base 13 ofthe bowl 1, is provided tofit around thetop of the aforesaid casing, upon which latter said base is adaptedto're'st, and a central, vertical, screw-threaded, inlet opening 14, insaid base, is provided for the upper terminal of the aforesaid supplypipe or equivalent member, which opening or passage continues up throughthe nipple 8.. The passage or inlet 14 and the continuation of suchpassage through. the nipple 8 and Patented May at, 1920..

the sleeve 6 and into the dome 9 have a common axis which is in thecenter of the bowl 1. A waste passage 15, in the base 13, opens at thetop through the bottom of the bowl, and at the lower end into the spacewithin the flange 12.

It will now be seen that the supply of water to the fountain enters thepassage 1.4-, flowing in the direction indicated by the adjacent arrow,in Fig. 2, and passes through the base 13, nipple 8, and the upper partof the sleeve 6 into the dome 9, out through the opening ll in said domeinto the chamber 10 in the nozzle 3, and through said chamber and themonth t of said nozzle. It will be seen, further, that, owing to thelocation and inclination of the mouth 4-, the stream of water, uponleaving said mouth, must continue upwardly and toward the axis of thebowl 1 and beyond such axis until drawn by gravity into said bowl, thepressure of the water being regulated, by the means to which referencehas been made, to insure the deflection of said stream to the necessaryextent before the water is projected over the edge of the bowl. Theoblique direction of the stream of water immediately upon leaving themouth 4 is indicated by the associated arrow, in Fig. 2. The point atwhich'the mouth is applied to the stream for the purpose of obtaining adrink is at such a distance from the mouth 4 that no portion of saidstream with which-the lips of the person drinking come in contact doesor can return to the orifice whence the stream comes.

In practice the stream rises obliquely from the mouth 4 and is projectedto a point approximately over the inner, closed end portion of thenozzle 3, which portion is in the center of the bowl, at or a little beyond. which point preferably the mouth of the person desiring to drinkis applied. After passing the aforesaid point the stream falls into thebowl at some distance from the outlet of the nozzle or the mouth 4.

The water in the bowl escapes through the passage 15. The velocity orforce of the water at and adjacent to the mouth prevents a' person fromattempting successfully to drink at that point, and compels such personto take the drink from the stream at a sufiicient distance from the saidmouth'to obviate all possibility of contaminatingthe same. In order todrink to the best advantage theperson should interpose the mouth in thepath of the stream at approximately the point where said stream beginsto change from an upward to a downward course. q It is now clear thatgerms from the moutl .Of a person canbe deposited on the water outletportion of the nozzle neither by direct appli:ati on of are lips to suchpen tion of said nozzle, or indirectly by the falling back on saidnozzle or said portion thereof of the water after contact with saidmouth or lips. This fountain is, therefore, entirely sanitary in theparticulars herein pointed out, as hereinbefore stated.

The perforated dome 9 protects the interior supply members from foreignsubstances or matter that might, by accident or design, find the way orbe introduced into the nozzle 3, which could occur only while the waterwas shut off below the passage 14; and said dome also serves as a checkon the water or a means to control the flow of the same, in addition tosuch other means as may be provided for that special purpose.

The nozzle 3 can be unscrewed from the sleeve 6 and the latter from thenipple 8 in the event it becomes necessary to clear or clean out theparts. In this connection attention is called to the facility with whichthe nozzle of the old type, which has its axis in common with the. axisof the bowl, can be replaced with the new nozzle, it being necessarymerely to unscrew the old part or parts. accordingly as only the nozzleproper or both said nozzle and the sleeve must be changed, and screw onthe new part or parts. This is an important and valuable feature.

More or less change in the shape, size. construction, or arrangementofsome or all of the parts of this fountain may be made withoutdeparture from the spirit of my invention.

I am aware that means in drinking fountains for proiecting a stream or aplurality of streams of water horizontally or obliquely have been usedbefore,and do not therefore. seek to claim such means broadly.

What I claim as my invention, and desire to secure by Letters Patent, is

1. As an improved article of manufacture,

'a drinking-fountain nozzle comprising a horizontal member havingtherein bottom and top openings at opposite ends, respectively, and alongitudinal passage with the bottom of which at one end said bottomopening communicates, and with the top of which at the other end'saidtop opening communicates, a separable inlet sleeve at tached to said.member ,and extending through said bottom opening, and having aperforated dome within said member and communicating with said passage,the major axis of said -member being approximately at right-angles tothe axis of said sleeve, and the axis of said top opening being obliqueto the axis of said sleeve.

2. The combination, in a drinking fountain, with a bowl having a centralvertical inlet, of an approximately horizontal nozzle having an inlet inthe bottom adjacent to one end. and attached at such endfo said bowlover said first-named inlet, said nozzle extending laterally from theaxis of said first-named inlet, having in the top adjacent to the otherend an outlet the axis of which is oblique to said first-named axis,also having a communicating passage between the inlet and outlettherein, and being an integral member which has therein said bot tominlet adjacent to one end, said top outlet adjacent to the other end,and said con1- municating passage between said inlet and outlet.

3. The combination, in a drinking fountain, with a bowl provided in thebottomwith a central nipple, and having a vertical inlet opening throughsaid nipple, of a removable sleeve mounted on said nipple, said sleevehaving a perforated dome, and an approximately horizontal nozzle mountedon and removable from said sleeve over said dome, extending laterallytherefrom, and having in the outer terminal an outlet the axis of whichis oblique to the axis common to said nipple and sleeve, the connectionbetween said sleeve and nozzle being in the bottom adjacent to one endof said nozzle.
